First light for the Winter season 2019-20, latest ever
I haven't post any new images since March 4. 2019, this is the first light for this Winter season!
I have had some technical problems with my "new" imaging system and the weather up here has been really bad for several months.
I have had some technical problems with my "new" imaging system and the weather up here has been really bad for several months.
The new imaging system is kind of temporary solution, since I'll have new camera and optical configuration in near future. The current system is interesting combination, a massive Apogee Alta U16 camera and filter wheel is mated with Tokina AT-x 2.8 camera lens. To make this combo to work, I had to modified the camera lens heavily. I cut a way part of the lens body with the angle grinder to have enough back focus distance. (I cut a way aperture control ring and filter holder part of the lens since they are not needed in astrophotography.) I'll post some pictures soon. EDIT, here are some info and images about this configuration
First light for the Winter 2019-20, IC 1396

Image is in mapped colours, from the emission of ionized elements, R=Sulphur, G=Hydrogen and B=Oxygen. The signal for ionized oxygen,.

Not a bad resolution for a 300mm camera lens!
There are a tiny planetary nebula PM 1-333 visible in this image, as a howk eyed Jussi Kantola pointed out in Facebook.

The planetary nebula candidate at middle left stands out well in this starless photo of IC 1396 area.
INFO
H-alpha, 12 x 600 s, binned 1x1 = 2 h
O-III, 6x 600 s, binned 2x2 = 1 h.
S-II, 3 x 600 s. binned 2x2 = 0,5 h
Just left from the IC 1396 seems to be a circular formation with some weak O-III emission. Could this be a planetary nebula? I must check this soon from the astronomical database or if somebody knows this, please. let me know.
UPDATE!
UPDATE!
Ny friend Sabik Rasool, a planetary nebula enthusiast, Find out that this formation is a HII area discovered in 2015. This doesn't rule out, that this could be an ancient planetary nebula though.

IC 1396 spans hundreds of light years at distance of about 3000 light years in constellation Cepheus. The famous formation of glowing gases, the "Elephant's Trunk Nebula" can be seen at four o'clock position.
This is an active star formation region and it has several massive young stars inside it, coursing the ionization of elements of this emission nebula.

Happy New Year 2020
The year 2019 was very quiet regarding astronomical imaging. I'm building up a new imaging system with new optics and camera. Lots have been done though, I have been in many imaging conferences as a speaker. Beside that, I have been working in a book project with some of the most famous names in the world. I'll wrote more about this book next year before it's published at Spring 2020!
